This load dump function is required for almost all automotive electronics; all vehicle manufacturers test to rules: ISO 7637 : 2004, ISO 16750-2 : 2010, JASO and Toyota TSC7001. Load Dump Conditions Surge voltage is generated by alternator when battery is disconnected in engine operating status (alternator is supplying electricity). 26# VISHAY DIODES Operation of Load Dump TVS Load dump TVS clamps the surge voltage and bypasses the energy through the device to protect vulnerable electronic circuits.
